Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Got several "rapid prototyping" quotes - Polyjet and SLA methods.
It's going to be more expensive than doing it on campus (~$125 per tray and lid using design studio).
Outsourced 3D prototyping will have higher quality (layers of 0.05 mm as opposed to 0.25 mm). Design studio 3D Printer would require additional heavy fill primer and sanding.
Got one quote on injection molding
~$6000 for mold tooling
Each tray (not including lid) is about $4 to produce (qty of 100); therefore 25 samples ~$100 (but there's the upfront cost of tooling!)
Looking at SolidWorks changes needed for injection molding: Surfacing instead of lots of fillets; Draft angles and thicknesses
Looking at CNC possibilities -- Talk to Tom and Isaiah at the Machine Shop for possible pricing info and other details
Created several whale shapes and other designs based from the sponsors sample artwork
3D printer was down, so no 3D print done
Accomplishments from Previous Week
Discussed Risk Reduction PowerPoint overview and presentation.
Continued SolidWorks model - focus on whale design.
Drew up some other possible shape designs based on the sponsors sample artwork.
Discovered possible online stores for suction cup possibilities: www.anver.com; www.allvacindustries.com
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Narrow down shape designs to one (Some possibilities are whale, penguin, elephant)
Start making SolidWorks models based on the chosen shape design, two prototypes with the same animal shape:
Interlock
Snap on lock
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
3/19/12
Liked the latest whale shape, but is open to other animal shapes
Wants to have two physical prototypes with both lid features
Suggestion to survey more mothers (in addition to the sponsor herself)

3/20/12
A lot of input on shape design, though most of them were considered already
Generic shape like circle
Other shapes like fish, Spongebob, face
Suction force to fasten lid (create vacuum in food compartment)
Too much detail in presentation making it too long
Risks and Areas of Concern
Lid integration
Suction cup integration

Schedule
Narrow down shape designs by 4/2/2012, show the best ones to the sponsor.
Ready to CnC one prototype by 4/9/2012.
Budget (list amount spent and amount remaining)
Budget increased to $1000, none spent
